BACKGROUND OF THE INVENTION

1. Field of the Invention

The present disclosure relates to liquid crystal display technology, and more particularly to a liquid crystal panel and the array substrate thereof.

2. Discussion of the Related Art

In order to solve the color issues of the liquid crystal panel, a design solution of charge sharing is usually adopted. With respect to the liquid crystal devices (LCDs) of 2D and 3D, when the 3D display mode is activated, flicker may occur in the 3D displaying images if the charge sharing function of the LCD fails due to frame rotation failure.

To enhance the flicker issues, usually, the pixel charging and the pixel sharing functions are independently controlled. One output of the gate driving chip corresponds to one charge scanning line or a common scanning line. However, the number of the gate driving chip has to be doubled, which increases the manufacturing cost.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Embodiments of the invention will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown.

FIG. 1 is a schematic view of the array substrate in accordance with a first embodiment. The array substrate 10 includes a 2D (two-dimension) displaying mode and a 3D (three-dimension) displaying mode. As shown in FIG. 1, the array substrate 10 includes a substrate 11, a plurality of scanning lines 12, a plurality of data lines 13, and a switch controller 14.

The scanning lines 12 and the data lines 13 are configured to intersect with each other on the substrate so as to form a plurality of pixel cells 15. Each of the scanning lines 12 includes a first scanning line 121 and a second scanning line 122. When the first scanning line 121 is turned on, the corresponding pixel cell 15 is charged. When the second scanning line 122 is turned on, the corresponding pixel cell 15 shares the voltage. That is, the pixel cell 15 connected with the second scanning line 122 shares the voltage.

The switch controller 14 respectively connects with the first scanning line 121 and the second scanning line 122. In the 2D displaying mode, the switch controller 14 turns on the first scanning line 121 and the second scanning line 122 in turn to implement the charging and the voltage sharing function. In the 3D displaying mode, the switch controller 14 turns on the first scanning line 121 and turns off the second scanning line 122. Thus, only the charging function is implemented, which improves the flicker issue in the 3D displaying mode so as to decrease the manufacturing cost.

The N-th pixel cell will be taken as one example hereinafter, wherein the N-th pixel cell 15 includes an N-th main pixel cell 151 and an N-th sub-pixel cell 152, and N is an integer larger than or equal to one.

The array substrate 10 further includes a first thin-film transistor TFT (T1), a second TFT (T2), a third TFT (T3) and a sharing capacitor (C) arranged correspondingly to the N-th pixel cell.

The N-th main pixel cell 151 connects with the drain of the first thin-film transistor (T1), the gate of the first thin-film transistor (T1) connects with the first scanning line 121, and the source of the first thin-film transistor (T1) connects with the N-th data line 13. The N-th sub-pixel cell 152 connects with the drain of the second TFT (T2), the gate of the second TFT (T2) connects with the N-th first scanning line, and the source of the second TFT (T2) connects with the N-th data line 13. The gate of the third TFT (T3) connects with the N-th second scanning line 122, the source of the third TFT (T3) connects with the N-th sub-pixel cell 152, and the drain of the third TFT (T3) connects with the sharing capacitor (C). That is, the drain of the third TFT (T3) is grounded via the sharing capacitor (C).

The outputs of the switch controller 14 respectively connect to the N-th first scanning line 121 and the N-th second scanning line 122. The input end of the switch controller 14 connects with the scanning driving signals.

In the 2D displaying mode, the switch controller 14 turns on the N-th first scanning line 121. That is, the N-th first scanning line 121 receives the high level scanning driving signals, and the first thin-film transistor (T1) and the second TFT (T2) are turned on at the same time. The N-th main pixel cell 151 and the N-th sub-pixel cell 152 connect with the N-th data line 13. The N-th main pixel cell 151 and the N-th sub-pixel cell 152 are charged via the N-th data line 13 so as to implement the charging function. After the N-th main pixel cell 151 and the N-th sub-pixel cell 152 are charged completely, the switch controller 14 turns on the N-th second scanning line 122. That is, the second scanning line 122 receives the high level scanning driving signals and the third TFT (T3) is turned on. The N-th sub-pixel cell 152 connects with the sharing capacitor (C). The N-th sub-pixel cell 152 shares the voltage with the sharing capacitor (C) such that the voltage of the N-th sub-pixel cell 152 is smaller than the voltage of the N-th main pixel cell 151. In this way, the voltage sharing is achieved so as to improve the color shift issue when the viewing angle is large.

In the 3D displaying mode, the switch controller 14 turns on the N-th first scanning line 121 and turns off the N-th second scanning line 122. That is, the N-th first scanning line 121 receives the high level scanning driving signals, and the N-th second scanning line 122 receives the low level scanning driving signals. The first thin-film transistor (T1) and the second TFT (T2) are turned on at the same time, and the third TFT (T3) is turned off. The N-th main pixel cell 151 and the N-th sub-pixel cell 152 connect with the N-th data line 13, and are charged by the N-th data line 13 so as to implement the charging function. In this way, the flicker issue in the 3D displaying mode may be improved without increasing the gate driving chip, and thus the manufacturing cost is prevented from getting higher.
